i think we can make mindjacked abby work! rita can either watch on in horror, try to intervene too early and get subdued (or forced to take the chip, ever wanted to join a hivemind rita?), or intervene shortly before the rest of clarke's friends bust in!

but of course, if none of those sound fun for you i can also offer: abby greeting clarke fresh out the skybox (rita'd blend right in with the other delinquents) or abby comforting clarke while she literally tries to scrub blood off her hands. OR! late s4 abby telling her teenage daughter to go save the world like, twelve hours before the second nuclear apocalypse wheeze
